Slovenian rescuers hopeful they will bring out 5 people trapped in a cave since Saturday

Slovenian rescuers are hoping to extract five people who have been trapped in a cave for two days because of high water levels

LJUBLJANA, Slovenia -- Slovenia's rescuers are hoping on Monday to extract five people who have been trapped in a cave for more than two days because of high water levels.

The rescue operation should be completed by mid-afternoon if everything goes as planned, said Sandi Curk, who is coordinating the effort.

A family of three adults and their two guides got stuck in the Krizna Jama cave in southwestern Slovenia on Saturday because of heavy rainfall.

The 8-kilometer (5-mile) cave system with a string of emerald-colored underground lakes is accessible only in boats and rafts and with a guide.

The group entered on Saturday morning but got stranded as subterranean waters rose swiftly. The water levels dropped by Monday, raising hopes they can be brought out.
